Title: A piece turning apparatus for selectively turning elongated pieces of lumber carried in sequence by a conveyor
Inventor: PERREAULT MARTIN
IPC: B27C7/00
Filed: 2005-01-07
Abstract: A system for selectively turning elongated pieces comprising a conveyor transversally receiving and carrying in a sequence the elongated pieces along a transfer course. A piece turning apparatus is mounted next to the conveyor and has a number of turning hands in which an end of one of the elongated pieces is engageable so that rotation of the turning hand effects a turning of the one of the elongated pieces about a longitudinal axis thereof when the end of the one of the elongated pieces is engaged in the turning hand. Carriages are distributively mounted onto the endless driving body and supporting respectively the turning hands so that each one of the turning hands successively moves into an engaging position with an end of one of the elongated pieces as the one of the elongated pieces is carried by the conveyor. A cam body drives the turning hands in rotation.

Patent CA-2553235-A1 (CA)
Inventor: WUNDERLICH GERD
IPC: A61K51/08
Filed: 2005-01-27
Abstract: The invention relates to a method for the production of particles labelled with the radioactive isotope Rhenium-188 (Re-188) and a kit for carrying out said method. Such radioactively-charged particles can be used in medicine, preferably in oncology and nuclear medicine, for the radiotherapy of tumours, or metastases of tumours. According to the method, the particles are suspended in a solution and heated, whereupon the solution firstly has a pH value of pH  1 to pH 3 and contains a tin-II salt and a Re-188 perrhenate salt. After 45 to 70 minutes of heating the pH value is increased. The suspension obtained after increasing the pH may be directly used for radiotherapy in patients. Radiation protection of the personnel is significantly improved as a result of the unnecessary washing step, along with a corresponding saving in time.  Furthermore, the requirement of tin-II salt for the labelling is reduced and the labelling yield is increased.

Title: Smooth handover in a wireless local area network
Inventor: TITTELBACH-HELMRICH KLAUS
IPC: H04L12/28
Filed: 2005-05-26
Abstract: The invention relates to a method for operating a data connection between a base station (AP1) and one or several mobile stations (MS1 to MS4), according to which data packets are transmitted between the base station (AP1) and the mobile stations within transmission phases, the beginning of each transmission phase (U) is indicated by issuing a starting signal (B), particularly a beacon signal, and the air interface between the base station and the mobile stations is managed by the base station during the respective transmission phase. The aim of the invention is to create a method which allows mobile stations to perform smooth handover processes to other base stations. Said aim is achieved by excluding each mobile station from the transmission of data packets during at least one subsequent transmission phase following the transmission of data packets while the mobile stations switch to a listening phase (M) during which radio traffic is monitored and another base station (AP2) that is suitable for transmitting data packets is searched outside the transmission phases used for transmitting data packets with the base station in order to prepare a handover process.

Patent CA-2569193-A1 (CA)
Inventor: BOBIER JOSEPH
IPC: H04B1/02
Filed: 2005-07-07
Abstract: A bandwidth control of sideband energy and compression method applied to the integer cycle methods of modulation, is now disclosed called X padding. Radio Frequency (RF) sine waves are grouped into frames of N cycles (divide-by ratio) where N is a variable power of 2 (i.e. 2, 4, 8, 16, 32, 64, 128, 256, 512, etc). This system is flexible wherein N can equal any one of these values. In the frame of N cycles, two alternate cycles are changed to the modulating frequencies. The other cycles remain precisely at the carrier frequency. The position of the alternate modulated cycles in a frame of N-cycles determines the exact binary bits that are being transmitted. This means that by sending only one modulation event where N =16, four (4) bits are transferred. For example, in a frame of 16 cycles (i.e. N =16) where the positions of the alternate modulated cycle is 6, then the four binary bits of information transmitted are 0110. X padding is used to set the pulse repetition rate to fit particular Power Spectrum Density (PSD) needs. This is done by inserting X number of un-modulated RF cycles to the beginning and to the end of the N Frame.
